Abstract: A design for repair casting having a repairable ultra-large single-piece casting and a replacement part. The ultra-large single-piece casting includes a main body portion, at least one predefined replaceable portion integrally cast with the main body portion, and a cut-guide delineating the predefined replaceable portion from the main body portion. The cut-guide includes a continuous channel defined on an exterior surface of the single-piece casting. The cut-guide further includes a rib extending from a channel wall on the main body portion. A damaged replaceable portion is excisable from the main-body portion by cutting through the single-piece casting along the cut-guide. The excised damaged replaceable portion may be replaced with the replacement part, which has substantially the same geometry, dimensions, and mechanical properties as an undamaged replaceable portion. The replacement part may be joined to the main body portion by mechanical means or by welding.

Abstract: A press casting die able to change its female and male die cores, in which mainly a movable-side fixed plate of a die seat is provided behind a male-die recess with a plate receiving recess of a larger area, the plate receiving recess can be mounted therein with a changeable pressure bearing plate having thereon holes for insertion of pushing-out pins, the pressure bearing plate is abutted against by a pair of die-foot blocks in its rear to thereby have sufficient bearing capability to assure its durability for a high pressure in material injection. Therefore, when life of use the die cavity is exhausted, only the female die core, the male die core and the pressure bearing plate are necessarily changed, thereby the cost of the die is largely reduced, and benefit of environmental conservation can be provided.

Abstract: The invention achieves a more effective die changing work, reduces a time required for performing die changing of work of a die, and improves an operational availability of a molding machine, in various kinds of molding dies. A die changing operation can be efficiently performed by drawing out an exclusive portion which is automatically attached to and detached from a general portion of a molding die, from the general portion by a feeding means and pressing the exclusive portion to the general portion. Further, the exclusive portion (an old insert) drawn out to a predetermined position from the general portion can be carried out to an outer side of a die casting machine by a carrying means, and another exclusive portion (a new insert) can be carried in to a predetermined position within the machine from the outer side thereof, within the machine in a die unclamp state. A subject to be treated by the feeding means and the carrying means in the die changing operation is only the exclusive portion, and the subject to die changing can be made compact and light in comparison with the case that a whole of the die is changed.
